The DeathVolt 16AWG Wiring Set contains 24 inches (2 feet) of both black and red wires that perfectly fit our heat shrink tubing, T-Plugs, or Tamiya connectors. These wires are super soft and flexible, unlike stiff dense crappy wires you may have used before. These are great for airsoft use in tight spaces! 16 gauge wiring is the standard for airsoft guns/gearboxes/battery chargers.See Youtube for demo videos on how to solder wires for use with T-Plugs, or other adapters. A must have if you purchase any of our custom battery plugs.
